* Then I measured and noted down the temperature of the water being heated as T2 which was also the temperature of the metal block and then I removed the metal block and immediately immersed it into the water in the calorimeter and straight away covered the calorimeter in order to avoid any heat loss to the atmosphere.

iv. I left the half filled calorimeter for few minutes in order to reach the state of equilibrium with room temperature. v. After some time I measured the temperature of the water from the calorimeter. vi. After keeping the bob for some time, I recorded the temperature of the water bath

= 528.29 J Kg-1�K-1 Evaluation & Conclusion The value that we get is 528 J Kg-1�K-1. Theoretically, the Specific Heat Capacity of Aluminium is 897J g-1 �K-1. I presume that we may have lost some of the heat to the air as well as to metal expansion.

and current (I) were constant. To maintain the experiment as fair as possible, the values for voltage and current were maintained constant. Voltage=12V (�0.01V), current= 4A (�0.01A) Uncertainty (U) of E= U of V + U of I + U of t U of Q= 0.01+0.01+0.01 => U of Q= �0.03J voltage ( �0.01V)

=> => => => = 648.6117433 J 650 Jg-1 Conclusion In this experiment, the latent heat of fusion of ice was investigated. By the results, it is accounted that the latent heat of fusion of ice is 650Jg-1. It was possible to draw a best fit line which accounted

Reaction turbines Francis turbines. Francis turbines are reaction turbines, with fixed runner blades and adjustable guide vanes, used for medium heads. In this turbine the admission is always radial but the outlet is axial. Photograph 6.3 shows a horizontal axis Francis turbine. Their usual field of application is from 25 to 350 m head.
